Understanding Goat Behavior and Fencing Needs

Goats are natural browsers rather than grazers, meaning they prefer to eat at eye level and will constantly test boundaries to reach tempting brush. Unlike sheep or cattle, they do not simply look down at the grass; they look up, under, and through any barrier in their path. A fence for goats must act as both a physical barrier and, more importantly, a psychological deterrent.

Physical fences alone can be expensive and inflexible for a rotational setup where pastures need to rest and regenerate. Portable electric fencing solves this by delivering a safe but memorable shock that teaches goats to respect the boundary. To make this work, the system must maintain high voltage constantly, as a weak fence will only invite goats to push through or climb over.

Goats have insulating hair coats rather than thick wool, which makes them highly sensitive to electric shock once they make contact, but their agility means they can easily jump low wires or squeeze through wide gaps. A successful portable setup requires tight spacing, reliable power, and rapid deployment capabilities to keep up with weekly pasture rotations.

Electric Netting – Premier 1 ElectroNet 9/35/12

Electric netting serves as the primary physical and psychological boundary for containing goats in temporary paddocks. It prevents kids from slipping through and stops adults from sticking their heads through the mesh to reach outer weeds. This pre-woven grid eliminates the tedious task of stringing multiple individual wires by hand.

The Premier 1 ElectroNet 9/35/12 is the gold standard for small-scale goat keepers due to its specific dimensions and construction. Standing 35 inches tall with 9 horizontal strands, it features close vertical spacings that prevent goats from getting their heads trapped. The built-in PVC posts are pre-spaced at 12-foot intervals, making setup a straightforward matter of unrolling and stepping the posts into the ground.

• Height: 35 inches
• Length: 100-foot rolls
• Best for: Standard and miniature goat breeds without horns
• Not recommended for: Horned goats or unenergized containment

Netting requires clean, mowed paths to prevent heavy vegetation from touching the live strands and draining the electrical current. It is highly compatible with uneven terrain, but saggy spots must be supported with extra stakes to prevent grounding out.

This netting is ideal for hobby farmers rotating small herds of standard or miniature goats through clean pastures. It is not suitable for horned goats who may get their horns entangled if the fence is left unenergized, nor is it meant for permanent, unmonitored perimeter containment.

Solar Energizer – Gallagher S100 Solar Charger

A solar energizer is the powerhouse of any remote rotational grazing system, converting sunlight into the high-voltage pulses needed to keep goats respectful of the fence. Without a reliable power source, even the best netting becomes a useless piece of string. Solar units eliminate the need to run long extension cords or constantly haul heavy lead-acid batteries back to the barn for recharging.

The Gallagher S100 Solar Charger delivers 1.0 joule of stored energy, which is more than enough to power up to 10 miles of single-wire fence or multiple nets. Its rugged, weatherproof casing is designed to withstand harsh pasture conditions, and the integrated solar panel is positioned to maximize sun exposure. It features a smart battery management system that keeps the fence hot for up to 21 days without direct sunlight.

• Stored energy: 1.0 Joule
• Power capacity: Up to 10 miles of single wire or 4 rolls of netting
• Battery backup: Up to 21 days without sunlight
• Best for: Sunny, open pastures far from mains power

To maintain peak performance, the solar panel must be kept clean of dust and oriented toward the midday sun (typically facing south in the Northern Hemisphere). It requires a dedicated ground rod setup—usually three galvanized steel rods spaced ten feet apart—to function correctly.

This unit is perfect for part-time farmers managing remote paddocks without access to mains power. It is not the right choice for massive, multi-acre setups requiring high-impedance mains energizers, or for heavily shaded woodlots where sunlight cannot reach the panel.

Step-In Posts – Zareba Heavy-Duty Step-In Post

Step-in posts are the backbone of customized, multi-wire portable fencing systems, allowing farmers to customize wire heights on the fly. They support the polywire or polytape at crucial tension points, especially around corners, curves, or dips in the terrain. These posts make it possible to build a pasture perimeter in minutes without digging holes or driving heavy T-posts.

The Zareba Heavy-Duty Step-In Post stands out because of its reinforced, molded-plastic construction and sturdy steel spike. It features molded clips at various heights, allowing for quick wire placement without extra insulators. The wide, heavy-duty step-in flange resists bending and breaking, even when forced into dry, compacted clay soils.

• Height: 54 inches total (48 inches above ground)
• Material: Heavy-duty UV-stabilized polypropylene with a steel spike
• Clip options: 8 built-in clips for various wire heights
• Best for: Interior paddock divisions and multi-wire polywire setups

While these posts are incredibly convenient, they can flex under heavy tension or high winds. When setting up corners, it is best to double-post or use a temporary wooden brace to prevent the corners from collapsing inward.

These posts are excellent for farmers using polywire to create customized internal paddock divisions for trained adult goats. They are not recommended as primary corner posts for high-tension wire, nor are they sturdy enough to contain large, untrained livestock.

Polywire Reel – Taragate Geared Reel 3:1

A polywire reel is essential for managing, deploying, and retrieving long lengths of electric wire without ending up with a tangled, useless mess. It allows a single person to walk out a fence line rapidly and wind it back up just as quickly during pasture rotation. Proper reel storage also extends the lifespan of the polywire by protecting it from UV damage and kinking.

The Taragate Geared Reel 3:1 features a heavy-duty gear system that turns the bobbin three times for every single turn of the handle. This high-speed retrieve saves significant time and forearm fatigue when winding up hundreds of feet of wire. The rugged plastic drum holds up to 1,600 feet of polywire and features a locking mechanism to keep the wire taut.

• Gear ratio: 3:1 retrieval speed
• Capacity: Up to 1,600 feet of polywire
• Materials: High-impact polymer drum with a galvanized steel frame
• Best for: Frequent pasture rotations and fast wire retrieval

The geared mechanism requires occasional cleaning to remove grit, dirt, and seeds that can jam the teeth. It is important to avoid over-tensioning the wire while winding, as excessive pressure can warp the plastic spool over time.

This reel is a must-have for farmers who rotate pastures weekly and need to move multiple lines of polywire quickly. It is overkill for small, static backyard pens where the fence is rarely moved or reconfigured.

Electric Polywire – Powerfields Extreme Polywire

Electric polywire replaces heavy, stiff steel wire with a lightweight, highly visible, and flexible alternative for temporary fencing. It consists of highly conductive metal strands woven together with UV-stabilized plastic threads. This combination provides the flexibility needed for frequent winding and unwinding while delivering the necessary electrical punch.

The Powerfields Extreme Polywire utilizes nine mixed-metal conductors, including copper and stainless steel, to deliver up to 40 times more conductivity than standard polywire. This ensures that the voltage remains high even at the far end of a long paddock run. The bright white and black weave provides excellent visibility, ensuring goats see the boundary before they touch it.

• Conductors: 9 mixed-metal strands (copper and stainless steel)
• Visibility: High-contrast white and black weave
• Conductivity: Up to 40 times more conductive than standard polywire
• Best for: Long paddock runs and low-output solar energizers

Polywire is designed for hand-tensioning only; using a wire strainer or mechanical tensioner will snap the plastic fibers. When splicing broken ends, use proper metal joiners rather than simple knots to maintain electrical conductivity across the break.

This high-conductivity wire is ideal for long paddock runs and setups powered by smaller solar energizers. It is not suitable for permanent perimeter fencing where trees might fall on it, or for animals that require a heavy physical barrier to stay contained.

All-In-One System – Gallagher SmartFence V2

An all-in-one system combines posts, reels, and wire into a single, integrated unit to maximize efficiency and minimize setup time. It eliminates the need to carry separate bundles of posts, reels of wire, and tools out to the pasture. This streamlined approach allows a single person to set up a four-wire temporary paddock in under five minutes.

The Gallagher SmartFence V2 is a revolutionary tool featuring four pre-strung polywires, ten integrated post standards, and a built-in winding reel system. Spanning up to 328 feet, it can be configured as a straight line, a corner, or a complete small enclosure. The tension is easily adjusted via the central hub, keeping all four wires perfectly spaced and taut.

• System length: 328 feet of four-wire fence
• Components: 10 integrated posts and 4 pre-spooled polywires
• Setup time: Under 5 minutes for a single person
• Best for: Fast, daily rotational grazing on flat to rolling terrain

Because the system is fully integrated, damage to a single post or wire requires specific replacement parts rather than generic farm store fixes. It works best on relatively flat or gently rolling terrain, as extreme dips can cause the pre-spaced wires to ground out on the soil.

This is the ultimate tool for busy hobby farmers who value speed and convenience above all else during daily or semi-weekly rotations. It is not ideal for rugged, brushy woodlots, nor is it cost-effective for farmers on a very tight budget who prefer piecing together individual components.

Battery Energizer – Cyclops Hero 12-Volt

A battery energizer provides a powerful, reliable shock for temporary paddocks where mains power is unavailable and solar panels might struggle due to heavy tree canopy. By drawing power from a standard deep-cycle marine battery, these units offer consistent output regardless of weather conditions. They are essential for brush-clearing operations in dense woods where solar chargers cannot get direct sunlight.

The Cyclops Hero 12-Volt is a heavy-duty, American-made energizer that outputs a powerful 0.75 output joules. It features exceptional lightning protection and a robust, weather-resistant case designed to sit out in the elements. Its low current draw ensures that a standard 12-volt battery will keep the fence hot for weeks before needing a recharge.

• Output energy: 0.75 Joules
• Power source: 12-volt deep-cycle marine battery (not included)
• Protection: Built-in lightning diverters
• Best for: Shaded woodlots, orchards, and brush-clearing operations

Users must monitor battery charge levels regularly, as a deep-cycle battery should not be discharged below 50% to ensure a long lifespan. A high-quality battery charger is required at the home base to recharge the batteries between uses.

This unit is perfect for farmers grazing goats in wooded areas, orchards, or under heavy shade where solar units fail. It is not necessary for open, sunny pastures where a solar-integrated unit offers more convenience, or for small backyard plots close to an outdoor mains outlet.

Lead-Out Cable – Patriot Undergate Cable

A lead-out cable is the critical link that carries electrical current from the energizer to the fence line, or under gates to maintain continuity. Standard household wire is insulated only for 120 or 240 volts and will quickly leak high-voltage fence pulses (which range from 5,000 to 10,000 volts). This specialized, heavily insulated cable ensures the power gets to the pasture without shorting out on posts, gates, or the ground.

The Patriot Undergate Cable features high-quality galvanized steel wire encased in thick, UV-resistant polyethylene insulation rated for up to 15,000 volts. This heavy insulation prevents voltage leakage even when buried directly in the soil or run along metal gates. The galvanized core matches the metal of most fence components, preventing the galvanic corrosion that occurs when mixing copper and steel.

• Voltage rating: Up to 15,000 Volts
• Wire gauge: 12.5 gauge galvanized steel
• Insulation: Thick polyethylene jacket
• Best for: Connecting energizers to fences and running power under gates

When burying this cable under gates, it should be run through a piece of plastic conduit to protect it from rocks, vehicle traffic, and digging pests. Ensure all connections are wrapped tightly and secured with joint clamps to maintain a solid electrical path.

This cable is necessary for any setup where the energizer is mounted inside a barn or where power must jump across a gate opening. It is not needed for simple, self-contained pasture setups where the solar or battery energizer is clipped directly to the netting.

Designing Your Rotational Grazing Paddocks

Successful rotational grazing relies on dividing your pasture into smaller sections, or paddocks, to control where and when your goats graze. This prevents them from cherry-picking their favorite plants and overgrazing them to death while leaving less desirable weeds to take over. The ideal paddock size depends on your herd size, the quality of the forage, and how frequently you plan to move the fence.

When mapping out your paddocks, you must plan for daily water delivery and shade access. Creating a central "hub" or alleyway that leads back to a permanent water trough and shelter can save you from moving heavy water tubs every time you shift the fence. If a hub isn’t feasible, invest in lightweight, portable water tubs and mobile shade structures that can easily roll with the herd.

The golden rule of rotational grazing is to allow grazed paddocks sufficient time to rest and regrow before returning the goats. Most pastures require 21 to 35 days of rest, depending on the season and rainfall, to rebuild root systems and prevent parasite life cycles from completing. Never let goats graze pasture down below three inches, as this forces them to graze close to the soil where parasite larvae congregate.

How to Train Your Goats to Electric Fencing

You should never introduce untrained goats directly to a temporary, portable fence in a large pasture. Instead, set up a secure, highly visible training pen inside a permanently fenced area, such as a barnyard. Run a hot wire or set up a section of electric netting just inside the physical fence, ensuring there is no way for them to escape when they receive their first shock.

Introduce the goats to the training pen during dry weather, as wet ground increases the intensity of the shock and can cause unnecessary panic. Place a small amount of tempting feed just on the other side of the electric wire to encourage them to investigate it with their sensitive noses. Once a goat receives a sharp, high-voltage shock to its nose, it will quickly learn to back away and respect the boundary.

Keep the goats in this training setup for three to five days, monitoring them closely to ensure they all understand the barrier. Some goats may react by jumping forward rather than backward upon the first shock, which is why the permanent outer fence is crucial. Once the entire herd hesitates and turns back at the sight of the wire, they are ready to be moved to portable pasture paddocks.

Maintaining Your Portable Fence for Safety

The most common cause of portable fence failure is vegetation shorting out the live wires. Tall grass, weeds, and falling branches touching the fence will draw power away from the system, dropping the voltage to useless levels. Walk your fence lines regularly with a digital fence voltmeter to check for voltage drops and weed out heavy growth along the path.

Wind, wildlife, and curious goats can cause portable posts to sag and wires to lose tension over time. Check the tension of your polywire and netting weekly, adjusting step-in posts and corner braces as needed to keep the lines crisp and off the ground. Ensure all electrical connections, ground rod clamps, and jumper cables are tight and free of rust or corrosion.

When a paddock is not in use, store your netting and polywire on reels in a dark, dry place out of direct sunlight to prevent UV degradation. Inspect the plastic fibers of your polywire for fraying and replace any damaged sections before the next grazing season. Taking care of your gear during the winter ensures it will be ready to perform flawlessly when the spring flush arrives.

Implementing a robust, portable fencing system is the key to unlocking the full potential of rotational goat grazing on your hobby farm. By selecting the right combination of high-voltage energizers, durable netting, and reliable polywire, you can keep your herd safe while improving your pasture health. With a little training and regular maintenance, these portable systems will provide years of hassle-free grazing and happy, healthy goats.
